I have been racing on this tire for years - great all around tire. The crew at Ride CX are easy to work with and get the product shipped quickly.

Have about 200 miles on these tires with two cx races one of which was wet conditions. Tires are surprising good for a file(ish) tread. Hook up well and roll nice. Predictable. Have been pleasantly surprised. Actually like these better than the grifo tires. Quickly becoming a go-to. Impressed!

Hey had the tires I wanted and shipped them to me promptly. So better than Bezos.

Challenge Chicanes are the absolute best dry/mixed conditions tire! Light, supple, and resilient, although I tore my palms up mounting them! Excellent customer service at RideCX, I was looking for Chicanes for a local CX race and couldn't find them anywhere around Boise area bike shops. Every other online shop couldn't expedite shipping to receive before the race. I called rideCX and they were able to get me the tires the day before the race! So thankful for the amazing customer service they provided 🙏

Great product! Much cleaner product than what I’ve been using. Great service and prompt delivery from rideCX

I've been riding the Strada Bianca 700x36 TLR tires now for 4 months. They are a pleasure to ride, as they are very supple and the Challenge Smart sealant has been retaining air better than any other Tubeless Ready tires that I've owned. Topping off to 35 PSI is only needed every couple of rides.
They required no tire levers when I installed them in the industry recommended manner. I introduced the Sealant through my Reserve Wheels Fillmore valves and the tires popped into the rims very nicely.
I've put myself through more than my share of tire, valve, and sealant combinations, as I have bicycle shop experience and am a reference for my friends, who I don't care to mislead. With this being said, Challenge tires, Reserve Fillmore valves, and Challenge Smart sealant, are now my current standards.

I was very impressed with the customer service at RideCX. I had to make an a change on my order after placing it and contacted them by email. They were super responsive and helped me with my order. The item shipped fast and arrived on time. I’m very pleased with the Arundel shop inflator. The price is reasonable, it’s built very well and as far as I can tell it’s accurate. I compared it to my Silca floor pump and they are almost exactly the same pressure. I’d definitely order again from Ride CX.

One of my personal favorites.

Great for seating tubeless tires and topping up tires for group rides.

I was looking for a fast tire for a upcoming 120 mile gravel bike race. About 60 miles of the course was on very hard ground with exposed rocks. Arizona “gravel”. I was concerned with the difficulity that other had with mounting. I am using Reserve 32 wheels. I followed the instructions on the Challenge site and while a little more difficult to mount than other tires, I was able to with only needing to use a lever for the last few inches. I was able to seat the bead on one tire with my floor pump and the other needed compressed air. The ride on these was excellent. Very soft with lots of traction. I am coming from a set of Zipp tires and there were a much better ride. After riding a few rides (80 miles or so) I unmounted them and put them back on just to see how hard it would be after they had stretched some. I was able to re mount without needing any levers. All by hand. Again, I was able to seat one tire with my floor pump (the one that needed compressed air last time) and the other with my compressor. The 120 mile gravel race went well without any tire issues. A fast rolling, nice handling, and tough tire. I now have a few hundres miles on them and they are doing great. The mounting that others have had my be dure to the tire/rim combination.

Super service.

Donnelly MXP TLR vulcanized tires: both were mounted up and sealant added in less than 45min (including taking off my gravel tires :). Thanks for all of your help--you have a CX customer for life! BTW the 33 tire measures 36.5mm (sidewall to sidewall) on a 23mm inner rim--perfect for me.

A high-quality tire at a reasonable price. The box was unnecessary.

Perfect

I'm not a great CX Racer but my first race on these was a great experience. They are forgiving and dealt with a lot of speed, grass and bumpy terrain. Strong 5 stars.

RideCX really got me out of a jam as I received the tires just in time to mount them and get to the race course.
